We seldom use a ticket to take a train in Tokyo these days, because there's a well-developed payment system using non-contact IC cards. But today I asked my wife to go the railway service to set my IC card up as a fixed fee pass, and I didn't bring it with me. It made me buy a ticket at the station. At first I couldn't find the fare chart letting commuters to know the fee. Tokyo has a very complex railway system so there used to be a billboard to show the freight for every stations. Also there's a limited number of ticket-vending machines, far less than I remember.
